Sefar has developed a special polypropylene yarn to withstand strong alkaline process conditions at operating temperatures up to 110 degrees Celsius. Our multichannel bags feature highly uniform dimensions thanks to an automated fabrication process from cutting to welding and channel sewing on a special sewing automate. Special thread is used for sewing and a highest-class fabric allows for smooth installation and perfect tightness on the collector.

The SEFAR TETEX line comprises a complete range of monofilament, multifilament and mixed mono-/multifilament fabrics.

SEFAR TETEX fabrics all have uniformly distributed pores and a smooth surface as a result of special fabric finishing. Monofilament fabrics deliver outstanding filtration results. They do not clog during filtration and can be cleaned easily. Multifilament fabrics are used especially for their ability to retain very fine particles as well as their mechanical resistance. The mixed monofilament and multifilament mesh combine several of their most useful properties.
